In 2002 an amendment was added to the International Convention for the Safety of
Life at Sea (SOLAS) which opened up for shipbuilders to replace steel with lightweight
materials in the superstructures. However, SOLAS requires equal fire safety
compared to ships with steel superstructures.
LASS-c is a cross-organizational project with the aim to find a method to build cruise
ships with part of the superstructure made in lightweight materials. As a part of the
LASS-c project the purpose of this thesis has been to develop an application in Java
(FISPAT). The tool has been designed to find fire sensitive areas in structures such as
cruise vessels. A second aim with the thesis has been to evaluate the cruise ship
Norwegian Gem with respect to fire sensitive areas.
In FISPAT the user can make a model of a structure. The model is built up by rooms,
networks and devices. With the model, FISPAT can simulate fire spread and the
effects on the networks included in the model. The user can then analyze the results
to find fire sensitive parts.
One of the main results in this thesis is the tool itself together with this report which
also serves as a manual to FISPAT. An evaluation of Norwegian Gem was also made
which points to some critical parts of the ship. One example is the main water supply
pipe to the sprinklers which has no redundant systems and all sectioning valves are
manually operated, hence it is vulnerable to faults. The electrical feed to the three
pump units is also a vulnerable point on the vessel. The pumps have redundant
electrical networks, but the wires are drawn on the same paths, making it possible to
take out both systems with one fire.
